Level 2 - Design of an 8bit+8bit BCD Adder

You task is to design an BCD adder, that adds two two-digit BCD numbers. The structure of a 4bit BCD adder is as follows:

Your submission must include the following:

Design your BCD adder in VHDL; this must be structural for the top-level

Simulate your design and show correct behaviour; the input and output vectors must be shown in decimal
